SPECIFICATION forming part'of Letters Patent No. 741,620, dated October20', 1903. Y Application-filed November 20, 1902'. erial No. 132,128.(No model.)

To a/ZZ whom it may concern: i

Be it known that L'WILLIAM D. BEooKs, a citizen of the United States,residing at Baltimore, Maryland, have invented certain-new andt usefulImprovements in Can gMaking" for the can-bodies and to means for lockingand soldering the side seam of the saidbodi es.

The inventionis 4illustrated in the accompanying drawings, in'whichl.

Fig. 3 is a side view ofthe horn and bracket. Figs. 4 and 5 are side and end views of theregister or gage bar. Fig. 6 shows a side and end view of anothergagebar. Fig. 7 is a side view of azpresser-foot. Fig. 7 is a plan viewof Fig. 7. Figs. 8 and 9 are side andv plan views of the folding-`wings. Fig. 10 is a view of a lever. Fig. 11 is a View of a iiuX-tank.Fig. 12 is a detail view of a guide-Wheel for the can. Fig. 13 is aAview of the inner soldering-iron. Figs. 14 and 15 are detail views of alinx-bath.

for receiving the can-bodies from the horn.

Fig. 18 is a sectional view on line 18 18 of Fig. 1..

Fig. 19 is a side view of one of the breakingknives. Figs. Y2O and 21are detail views of the fixed breaking-knives.

The sheet-metal blank from which the canbody is to be formed is placedby the operator upon the table 1 and just in rear of a detent or detects2, pivoted to the said 'table and projecting slightlyl above the same.From this position the sheet-metal blank is moved toward the rear bycarrier means consisting of sliding plates'or blocks 3, secured byscrews 4 to dovetailed slide-bars 5, which move in guideways 6 inopposite sides of a bracket 7, secured to the face or theupright frame 8of the machine, which frame also supports the table 1, as shown in Fig.'1. The plates 3 each carry a series of pawls 9,

pivoted thereto, to feed the blank step by step rearwardly as saidplates are reciprocated through the connections consisting of the links1'0, a lever 11 carried by a rock-shaft 12 journaled in a bracket 13,the said shaft havingan arm 111 provided with a projection or roller 15entering a cam-groove in the face of the disk 16 on a shaft 17 journaledin bearings at the top of the frame, said shaft being rotated throughbeveled gearing 18 from a vertical shaft 19, which is driven throughbeveled gearing 2O from a main driving-shaft 21, which has the pulleys22 thereon. The rst rearward movement of the carrier means carries theblank beneath 'the bracket 7 to mechanism designed to break ithe edgesof the blank, so that they may be interlocked for forming the sideseams. In this position the blank is held by two of the detents 2'. Thebreaking means consist of presser-feet 23 23', pivotally supported oneon each side of the bracket 7. The presserfoot 23 is journaled iu abracket 24, and it is adapted to hold the blank by downward pressureupon the upper surface of a ixed breaking-knife 25, secured to asuitable bracket 26, suitably supported on the frame. The presser-foot23' for the opposite edge of the blank is pivoted to a bracket 23X andis adapted to press upwardly against a breaking-knife 25', secured to asuitable bracket 26', secured 'to' the'machine.

With these fixed breakingknives movable breaking-knives cooperate, oneof these (marked 27) being carried by a lever or arm 28, pivoted on thesame pin 23X y with the presser-foot 23. This breakingknife movesdownwardly in the breaking operation, while for the other edge of theblank the breaking knife 27 moves upwardlyf',

Each of these breaking-knives is of curved f;

form and when operated they bend the edge of the blank which projectsover the adjacent Xed breaking-knife 25 or 25', the one on the right ofFig. 2 bending the edge downwardly, while that on the left of Fig. 2bends the edge upwardly. Between the levers 28 or 28', carrying themovable breaking-knives,and the presser-feet springs 29 are interposed,so that as soon as the breaking-knives begin to move the springs will becompressed and i the l presser-feet will be forced with a yieldingpressure against the sheet-metal blank to hold it while the breakingoperation is being performed. In order to provide means for gaging theposition of the blanks in relation to the breaking-knives, I providebars 30, pivoted to the arms 28 28 and slotted at 3l to receive pins forguiding the arms in their movement. There is a pair of these arms foreach breaking device, and the arms of each pair are connected by across-bar 32X, which lies with its face at a slight distance from theedge of the fixed breaking-knife, so that the projecting edge of theblank will'bear thereagainst to be properly positioned. It will benoticed that these gage-bars move away from in front ot' the fixedknives as soon as the movable knives begin the breaking operation, sothat said operation will not be interfered with. After this breakingoperation has been performed the carrier means, through one of the pawlsthereonthe intermediate oue in this instance-will cause the blank to bemoved rearwardly one step, where it will be retained by one of thedetents on the table l, and while in this position iiux will be appliedunder the broken or upturned edge of the blank, so that when the brokenedges are interlocked and hammered down, as will behereinafterdescribed, the flux will lie well Within the joint, s0 thatthe solder will-f1nd its way to the innermost parts of the said joint.This flux-applying device consists of a bath 32, suitably supported, anda brush 33, operated through suitable mechanism to dip into the bath andapply the flux under the npturned edge as the blank passes bythe brush.After this fluxing of the edges has taken place the carrier means movethe blank another step rearwardly, this action being due to the last ofthe series of carrier-pawls acting on the blank. The blank now liesbeneath a former 3ft of cylindrical form, which projects rearwardlythrough an opening 35 in the main frame and forms a cylindricalprolongation to the rear of the said bracket 7. At this point the flatblank is bent up into cylindrical form, so that its broken edges willinterlock. When the blank has arrived under the cylindrical horn orformer, a block or plunger 35 rises and grips the blank against theunder side of the horn or plunger. This plunger is carried by a stem 36,operated by an arm 37 on a rockshaft 38, journaled in bearings 39,secured to the frame, the said rock-shaft being operated by an arm 40,having a roller 4l entering a cam-groove in the disk 42 on the shaft 21,before described. Immediately after the blank is gripped by this blockor plunger 35 a carriage 43 is moved upwardly in its guides 44, securedto the frame, so as to bring a pair of wings 45, pivoted to the saidcarriage, into position to fold the blank around the cylindrical former,the said vertical movement of ihe carriage being effected from a cam 46on the shaft 2l, which has a groove receiving a roller on the lower part43 of the carriage,

the upper and lower parts of the carriage being connected adjustably, asshown in Fig. l, by the screw-threaded bolt 47 and nuts 48. These wingsare operated by links 49, connected with levers 50, fixed on rock-shafts5l, suitablyjournaled in the frame, the said rocksha'fts being operatedfrom cams 52 on the shaft 2l through blocks 53, arranged to slide inways 5I on the frame, said blocks having rollers entering the groove inthe face of the cam 52 and being connected by links 56 and arms 57 withthe rock-shafts 5l. Through this mechanism the wings are folded uparound the horn or former and the ends of the blank interlock with eachother. One wing may move slight-ly in advance of the other, as inordinary practice. The horn or former is provided with a spring portion57', so that the end of the blank on that side will be held slightlyaway from the horn or former, with its bent flange extending inwardly,so that the other end of the blank maybe passed under the same tointerlock therewith. I utilize the connections 52, 53, 56, and 5l, justdescribed ,for operating the breaking mechanism, and for this purposethe rock-shaft 5l has arms 58 connected by links 59 with the arms 28 28.By this mechanism While the folding operation is being done at the hornor former the breaking operation is being done at the breakingmechanism.

After the blank has been folded and its ends interlock'ed I register theinterlocked edges directly over the groove 60 in the top of the horn forthe hammering operation, and for this purpose I provide aregistering-bar or gage 6l, carried by a slide (52, moving in a bracket63, secured to the upright frame or plate of the machine, the said slidebeing operated through a lever-and-link connection lkfrom a slide 65,moving in guideways 66, secured to the face of the said vertical plateor frame, the said block having a roller 66' connected therewithentering a cam-groove in the face of a disk 67 on the shaft 17, beforedescribed. The register-bar or gage is normally retracted away from thegroove in the former while the folding is being done, and it is advancedafter the edges are interlocked, so as to accurately register theinterlocked edges with the groove and against the end of the spring 57.

In order that the gage or register bar may advance while the wings arestill in their folded position, I cut away the wings at the points 67,Figs. 8 and 9,'s0 that the fingers or projecting portions 69 of theregister-bar may pass .through these recesses and get in registeringposition. Vhile the interlocked edges are thus held properly registered,a hammer 69 descends and presses the interlocked edges together to makethe seam. This hammer is carried by a block or carriage 70, slidingvertically in ways 7l on the vertical plate or standard of the machine,the said sliding block or carriage being operated through an adjustablelink 72 from a crank 73 of the IOO IIO

shaft 17. The cylindricalbody is now moved from oft the horn or former'by a pawl or A burner-tube 79 extends from the rear end of the horn intothis cage, so as to heat the can-'body blank. This tube is supplied withgas from a pipe 80, connected with a passage 81, extending verticallyfrom the bracket 7 and thence horizontally to the rear end of the horn.On this burner-tube and within the cage I support a soldering-iron 82 bymeans of arms 83, said iron consisting of a plate having a groove 84extending therein longitudinally and centrally. As the can-body passesthrough the cage liux is applied to the seam by a brush 84', carried byan arm 85, having a roller 86 moving over a camWay 87 on the receptacle88, containing the bath of iiux. The arm 85 is reciprocated by a lever86',

' pivoted at 87' and connected by a link 88 With a lever 89, which isoperated by a roller 90 thereon entering a cam-groove in a disk 91 onthe shaft 17. After 'passing the iiuxbrush the can-body passes beneath asoldering-iron 92, supported by an arm 93 on the standard 94, the saidsoldering-iron having an opening 95 extending therethrough for thepassage of the solder-wire, which is fed from the reel 96, supported onthe standard 94, through feed-rolls 97 98, the former of which isprovided With a ratchet-wheel 99, operated by a pawl 100, carried by alever 101, operated by a link'102 from the lever 1l, before described.

The groove in the internal soldering-iron is tinned, and as the can-bodypasses over this iron it -is heated, so that it is in proper conditionto receive the solder fed through the outer soldering-iron at 95.

The groove in the inner soldering-iron receives the seam and guides thesame, the said seam thus remaining uppermost and'being properly directedto the outer iron to receiveV the solder. l

` Below the internal iron a trough 106 is supported on the burner-tubeto catch any particles of solder or tin which may drop, the saidinternal iron having openings in the bottom of its groove, as at 84X.

1 The outer soldering-iron may be hea-ted by a jet 107.

It will be noticed from the above that the main frame of the machinecomprises an upright plate or standard, with the horn lprojecting on oneside thereon and the bracket 7 on the other side, together withthebreaking mechanism. It Will be noticed also that various connectionsare'inade to the operating elements from two cam-shafts, one`at the topand the other at the' bottom ofthe ma-A chine, and these variousconnect-ions are supported on the main frame.

The`iux-bath`32 is supported, as shown in Fig. 14, by a suitable bracket9 6 from the bracket 7. The flux-brush 33is carried. by an arm 97',pivoted to a lever 98', which is pivoted to a bracket 100', operatedfrom thel lever 89 through a rod 99. This mechanism is representative ofany which may be found suitable for the purpose. v

The arm 97l has a roller 101', which Works over a cam projection ortrack 102l on the tank of the bath to raise and lower the brush into andaway from the tank as the arm 97 is reciprocated. This mechanism acts inuni` son with and in a similar manner to that described in connectionwith the linx-brush 84.

On the rear side ofthe tank 32 a cam or incline 32 is placed. The stem33 of the brush is jointed at 33X, and-below the joint it isv providedwith a roller 33", which as the brush descends engagesl the incline andcauses the lower end of the brush-stem to be turned laterally, so thatthe brush kwill enter beneath the upturned liange ofthe blank.

In Fig. 14 the parts are in the position assumed byv them When the brush33 is Within the tank, and it consequently appears in dotted lines insaid iigure. The position of the brush when applying the flux under thebroken edge of the blank is also indicated in this figure, this latterposition being the lowermost one that the brush assumes.

After leaving the horn Ythe can-body is engaged by a guide wheel yorroller 103, having a flange or edge 104 to enter the crease'at the seam,and'thus guide the can-body,'so that its side seam will be helduppermost. guide-wheel is arranged at the front end of This IOO

the cage, being supported in a bracket 105.

Before leaving the guide rim or ange of this wheel the seam of the canengages the groove -in the internal iron', to be guided thereby.

Each linx-tank may be provided with a reservoirBS, Fig. 11, adapted tofeed the liux automatically, for which purpose it is connected with thetank at 88 and has an airpipe 88" reaching down to the level it isintended to maint-ain the flux. Y

Itv will be noticed that the pivots of the breaking-knives are arrangedback from the edge of the fixed knives, so that as the curved knivesswing on their pivots they will describe arcs passing close across theedges of the iixed knives, the concave sides of said arcs being towardthe edges of the fixed knives.
